Socket shield technique has been accepted as a promising technique to maintain alveolar ridge contour, while the root fragment may exhibited signs of resorption. In the present case a newly modified approach which avoid the dentin-implant interface was employed to reduce adverse effects. This case report was targeted to evaluate the feasibility of this modified approach in a clinical practice setting.

Clinical decisions regarding the stability and osseointegration of mandibular implants positioned using the bone expansion techniques are conflicting and limited. The objective was to evaluate the stability of implants placed using two surgical techniques, selected according to the initial width of the mandibular posterior edentulous ridge, with D3 bone density, during a 12-week period. Fifty-eight implants in 33 patients were evaluated. Thirty-two implants in 24 patients were positioned using the osteotome expansion technique, and twenty-six fixtures in 17 patients were installed using the conventional drilling technique...

Implant surfaces are continuously being improved to achieve faster osseointegration and a stronger bone to implant interface. This review will present the various implant surfaces, the parameters for implant surface characterization, and the corresponding in-vitro human cell-based studies determining the strength and quality of the bone-implant contact. These in-vitro cell-based studies are the basis for animal and clinical studies, and is the prelude to further reviews on how these surfaces would perform when subjected to the oral environment and functional loading...

The recently popularised socket shield technique involves intentional retention of a thin buccal section of the remnant root at the time of immediate implant placement to preserve the buccal crestal bone from resorption. The objective of this systematic review was to assess the literature available on the socket-shield technique and weigh its biological plausibility and long-term clinical prognosis. A Systematic Search was performed in PubMed-Medline, Embase, Web of Knowledge, Google Scholar and Cochrane Central for clinical/ animal studies up to May 2016 without restrictions of language, duration, and follow-up...

The traditional material for covering the implant abutment screw is cotton. As the implant-abutment junction flexes and wears overtime, leakage from the oral environment penetrates into the screw access chamber where the cotton pellet is located. The cotton serves as a scaffolding for the proliferation of anaerobic bacteria in the warm, oxygen free environment. The bacterial exudate causes foul odors and may cause additional inflammation of the peri-implant tissues. The use of PTFE tape or PVS impression material serves the same role as the cotton pellet, but forms a better seal and limits bacterial growth inside the implant and abutment...

The clinical condition involving dental implants, characterized by soft tissue inflammation, bleeding, suppuration and rapid bone loss is widely known as peri implantitis. The main objective in the treatment of peri-implantis is to arrest the progression of the disease and at the same time to keep the dental implant in the mouth solving the inflammations signs of bleeding and pain. The aim of this paper is to highlight the effectiveness of the use of titanium brush and antimicrobial photodynamic therapy (aPDT) to decontaminate the implant surface, in association with regenerative procedures by means of autologous bone and demineralized bovine bone mineral (DBBM) in the treatment of peri-implantitis defects...
